From 6ea3b980f058d9dbc79ba88c652d581fa2d00792 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 6 Feb 2014 05:46:11 -0300 Subject: [PATCH] [media] vb2: rename queued_count to owned_by_drv_count 'queued_count' is a bit vague since it is not clear to which queue it refers to: the vb2 internal list of buffers or the driver-owned list of buffers. Rename to make it explicit.
